This page lists technologies and projects that CELF
members are interested in the status of. This includes kernel patches,
new technology research, and middleware and user-space projects of key interest
for consumer electronics products. The projects may be
the topics of discussion at CELF meetings, and we plan to watch and
report the status of these technologies.

Please add any information you have about the technology items listed below!!

Latest Watchlist

The Status field in the table below indicates whether this feature is on track for being
mainlined. The When was last activity field indicates the kernel version number or date when
the last activity was noted for this feature. This could be the last kernel version where
bits from this patch were mainlined, or the last date of visible feature development activity outside
the main tree.

Nicholas McGuire was taking over maintainership from Tim Bird, with funding from CELF. Haven't heard much recently (as of June 2008)

ftrace

mainlined in 2.6.27

This was formerly the latency-trace features from the RT-preempt patch set, refactored for general use

printk-times (arch support)

fully mainlined?

April, 2005

Some arches had problems with accessing the clock too early in the kernel bootup sequence, but a new setup routine defers turning on the timestamping until after timekeeping is initialized

Status

When was last activity

Notes

KTimers

mainlined, but needs lots of porting to embedded architectures

2.6.23 / 2.6.24

Adding clock driver support for various architectures is an ongoing process

RT-preempt

some parts mainlined

current RT patches are still against 2.6.26

Next target is to integrate threaded interrupts in 2.6.29 - as discussed on LinuxPlumbers conference Oregon 2008

Xenomai

external project

2.6.25 - stable release, newer in development

Xenomai is a real-time development framework cooperating with the Linux kernel, in order to provide a pervasive, interface-agnostic, hard real-time support to user-space applications, seamlessly integrated into the GNU/Linux environment. Ready to deploy.

"TOMOYO Linux has only recently surfaced on the wider mailing lists; its reception has not been entirely friendly. This project's developers have some work to do if they are (1) to get past the same obstacles which have slowed AppArmor, and (2) show that their project is sufficiently different from AppArmor to merit inclusion as yet another security framework." (from Linux Weather Forecast)
